Find the bottle that was masked from the bottom to top with a 1" (2.5 cm) band. This is your Bottom Reservoir Bottle. Using 1" (2.5 cm) diameter drill bit, drill a hole in the bottom of the bottle. Go slow and steady when drilling so that the bottle will not collapse. It will take approximately 20-30 seconds before the bit will pierce the plastic.
-
Download and print the bottle cutting templates. Print them unscaled on a letter-sized piece of paper. It is a pattern for the Bottom Reservoir Bottle. Follow the directions on the sheet as to how to mount it to the bottle.

Trace the Water Hole onto the bottle.
-
While the paper pattern is still on the bottle, mark and poke the Suspension Holes in the side of each bottle near its base using a sharp razor.

Using a sharp razor blade, cutout the Water Hole.
